Humans are as animaline as their pets and follow each other around. Cats and dogs as I have been witness to. ( Other pets I am not aware of in any way similar, nor looking ) Humans, i.e. people, are tactile entities and even though they might lose their minds still often want to touch each other, as in old age homes with the ‘completely senile’, as there are those who seek each other out for touching, and wander around to find each other. They know not each other nor are aware of the names of each other ( nor anyone else ! ) but seek each other out for genital area touching and general touching and no sex able but are still capable of a lot of tactility, co-touching. It is all they have left. Shocking as this is for me when I find it out, I agree … LET THEM BE !!!!
